The characteristics of potassium diethyl- and dibuthyldithiophosphates as the inductors of iodine-azide reaction carried out electrolytically have been presented. The influence of the pH and concentrations of azide and iodide ions on the course of reaction was examined. The determinations have been carried out in the range of 1-20 nmol.

The review summarizes application of coulometry for determination of the sulphur compounds that induce the iodine-azide reaction. The article discusses advantages of the coulometric method. The influence of potassium iodide on induction coefficients is also described. Moreover, determination ranges of several inductors are presented and sensitivities of determination by different methods are compared.
